1) transmission access cover
变速箱检视盖
2) transmission case cover
变速箱盖
3) fuel tank cap access cover
燃油箱盖检视盖
4) gearbox cover
变速箱端盖
1.
The numerical analyses of noise radiation from a gearbox cover of motorcycle have been carried out by using FEM software MSC.
应用有限元软件Nastran与边界元软件SYSNOISE对摩托车变速箱端盖的辐射噪声进行了仿真计算分析研究,预测了外部声场辐射噪声声压,分析了声场声压与结构模态频率之间的关系,确定了辐射噪声的关键区域和频带,结果说明FEM/BEM方法是预测辐射噪声的有效方法,分析结果为我们下一步声学优化打下了基础。
2.
A majority of noise was radiated from its surface by vibration, especially the thin parts for example oil pan, air valve cover, gearbox cover etc.
噪声很大一部分是通过表面振动辐射出来的,尤其是壁面较薄零件,如油底壳、气门室罩、变速箱端盖等等,因此表面辐射噪声控制对车辆噪声控制具有很重要的意义。
5) transmission rear cover
变速箱后盖
6) transmission top cover
变速箱顶盖
